Molai aadu is a lesser known goat breed rearing for meat purpose in Tamil Nadu and not yet registered as distinct breed. So far no sincere efforts have been made for registration of this population of important genotype. Hence, the present study was carried out to document Molai Aadu goat by using the proforma developed by the NBAGR, Karnal. Molai aadu goat is very popular among the breeders and has spread to Salem, Namakkal, Karur, Erode and Tirupur districts. The goat is prevalently spread to Chithode, Kavundapadi, Sirivaloor, Nambiyoor, Kanjikovil and Nallampatty areas of Erode district. The Molai Aadu goat is moderate in size with musculature. The colour of the animal mostly white in colour sometimes varies from complete white to light brown shades. The average body weights in males at birth, 3month, 6month, 9month, 12month and two-four tooth age groups were found as 2.05, 7.50, 12.45, 15.0, 17.75 and 29.15 kg, respectively. The corresponding values for females were 1.85, 6.70, 10.50, 13.5, 16.0 and 26.35 kg, respectively. The average reproductive performance viz. age at first kidding, kidding interval and gestation length were observed as 14.45 months (Range 14-20 months), 8.14 months (Range 6-9 months) and 147.81 days (Range 145-151 days), respectively. About 32 per cent does have a tendency of giving birth to twins. The goat had good reproductive ability and recorded litter size with maximum of six kids. In situ conservation of the breed and establishment of elite nucleus herds in the Government farms may be undertaken.
